Answer:
NaHCO3 + HCl ——-> NaCl + H2O + CO2
Explanation:
A neutralization reaction is a chemical reaction between an alkali and an acid to give salt and water as the product.
In the case of carbonates and bicarbonates, an additional product is added. This additional product is carbon iv oxide.
Hence a neutralization reaction involving an acid and a carbonate or bicarbonate would yield water, carbon iv oxide and a salt as the product.
When brioschi reacts with hydrochloric acid, the products are sodium chloride, water and carbon iv oxide.
The equation of the reaction is shown below:
NaHCO3 + HCl ——> NaCl + H2O + CO2
Answer:
See below.
Step-by-step explanation:
The author is probably reminding us that knowing the origins of words helps us to remember what they mean.
If "verde" means "green", the "verd" in "verdigris" probably means that verdigris is green.
However, the "verd" in verdigris domes from other languages.
It was originally Latin "viride aeris" (green brass).
In old French it became "verte de Grèce" (green of Greece). The modern French spelling is "vert-de-gris" (green of grey).
The English word "verdigris" comes from the French words.

Answer: 12.78ml
Explanation:
Given that:
Volume of KOH Vb = ?
Concentration of KOH Cb = 0.149 m
Volume of HBr Va = 17.0 ml
Concentration of HBr Ca = 0.112 m
The equation is as follows
HBr(aq) + KOH(aq) --> KBr(aq) + H2O(l)
and the mole ratio of HBr to KOH is 1:1 (Na, Number of moles of HBr is 1; while Nb, number of moles of KOH is 1)
Then, to get the volume of a 0.149 m potassium hydroxide solution Vb, apply the formula (Ca x Va)/(Cb x Vb) = Na/Nb
(0.112 x 17.0)/(0.149 x Vb) = 1/1
(1.904)/(0.149Vb) = 1/1
cross multiply
1.904 x 1 = 0.149Vb x 1
1.904 = 0.149Vb
divide both sides by 0.149
1.904/0.149 = 0.149Vb/0.149
12.78ml = Vb
Thus, 12.78 ml of potassium hydroxide solution is required.
